<h3 id="rationale">Rationale:</h3>
<p>ShellCheck has found a unary test operator that does not appear to be
followed by a valid shell word.</p>
<p>This could be because of a misplaced <code>]</code>, <code>)</code>,
or a missing space before the <code>]</code>.</p>
<p>Check the syntax, make sure the test operator has an operand, and try
again.</p>
